Forms
στερεός (stereós) m (feminine στερεᾱ́, neuter στερεόν); first/second declension[1]
Etymology
It probably comes from *στερεϝός (*sterewós), a formation like ἐτεός (eteós, “true”) and κενεός (keneós, “empty”).[2][3] Attic στερρός (sterrós) developed from it.[2][3][4] It is built on the Indo-European root Proto-Indo-European *ster- (“stiff, firm”), seen in Old High German starablint (“blind”), Proto-Germanic *staraz (“stiff”) and Tocharian B ścīre (“hard”).[2][1][4]
Earliest recorded meaning
Homer has the adverb στερεῶς, “firmly”, in the Iliad (9.510), and the adjective for firm ox-hide shields (Iliad 17.493) and for hard stone or iron (Odyssey 19.494).[5][6][7]
Semantic evolution
In Classical Greek it is firm, hard or solid: of ground and bones (Euripides, Plato, Xenophon), of solid gold (Herodotus), and of strong cloth.[7][6] Democritus, as Aristotle reports, set the solid against the void.[6] Of money and measures it meant standard, of full value, and Euripides and Aristotle use it rarely for barren.[2][1] Geometers used it for solid bodies and cubic numbers, whence στερεομετρία (stereometría) “stereometry” (the Epinomis, Aristotle).[2] Figuratively it was stubborn, hard, cruel.[1]
Its derivative στερέωμα (steréōma) meant a firm framework and the firmament.[2] Modern Greek στερεός is learned, partly a semantic loan from French solide.[8] French stère (1798), the cubic metre, comes from it.[9]
